Amazon announced today that it’s introducing a new “Mobile Associates API” for Android and Kindle Fire devices allowing developers to offer Amazon.com goods as in-app purchases and earn a percentage of sales in the process. Developers will earn up to 6% off purchases made through their apps and all sales will go through Amazon’s secure 1-Click purchasing and Amazon Prime shipping.

Amazon described a few of the possibilities for developers:

Until today, if developers wanted to create additional revenue channels for their apps they could use a “freemium” model with digital in-app purchasing or subscriptions, or by using mobile ads… App and game developers as well as existing Amazon Associates can create new and compelling user experiences within apps and games in three ways: selling a single item from within an app or game, showcasing a category of goods, or bundling the purchase of physical goods with the purchase of digital goods (for example, the customer receives a digital version of a board game when they buy the physical one). Animoca, Fismos, Days of Wonder and Spring2Partners are already integrating these experiences within their popular apps and games.
